Patented Apr. 15, 1930 PATENT OFFICE EUGENE P. FORRESTEL, J3 BUFFALO, NEW YORK BATCH BOX Application filed April 4, 1929. Serial No. 352,528.

My invention relates to new and useful improvements in batch boxes and the present application is a companion to one on batchboxes and grappling means therefor, filed of e even date herewith.

An object of the invention is to provide a batchbox with a central compartment to hold water andto provide means whereby, when the doorsof thebatchbox are opened, they will automatically open the discharge of the compartment so that the water may mix with i the aggregates as they pass from the bucket. Still another object of the invention is to provide a batchbox of the drop bottom door type having a central compartment that in reality forms hoppers in the box, and in turn,

is also used as a water compartment. There is also provided a discharge mechanismwhereby, when the doors are opened, the Water is allowed to flow from the compartment, and when the doors are closed, the water is automatically turned off.

Still another object of the invention is to provide a batchbox of the drop bottom type r H provided with a central compartment that forms a part of the bottom of the box, acts as a stop for the doors, strengthens the box, and forms a tank for providing water for the aggregates.

Still another object of the invention is to provide a batchbox that may be used withthe form of grappling means shown in the companion case or may be used with other forms of grappling means, and wherein a definite 1 3 and determined amount of water may be placed in a special compartment, so that further watering of the aggregates will not be necessary.

Still another object of the invention is to provide a batchbox that is exceedingly strong in service, cheap to construct and provided with automatic features for discharging water from a compartment formed in the a 5 batchbox.

With these and other objects in view, the invention consists in certain new and novel arrangementsand combination of parts, as will be hereinafter more fully described and pointed out in the claims. 7 a a In the drawings, showing a preferred embodiment of my invention,

Fig. 1 is a front view, parts being broken away for the sake of olearness;

Fig. 2 is a side elevation showing the rack and pinion connected with the water discharge andshowing in dotted lines the parts in their operated position; and

Fig. 3 is a sectional view taken on the line 3'3 of Fig. 1.

Referring now more specifically to the drawings, there is shown a batchbox 1 having the drop bottom doors 2. There also may be seen the straps 8, which are pivotally secured at their lower ends to the doors, and connected at their upper ends to each other and to a guide member 4. This guide member is held in position by the straps 5 that are, in turn, secured to the sides of the box.

At the upper ends of the arms or straps 3, on each side of the box, is a book 7 which is designed to fit within the end links 8 of the chains 9. a

As will be seen in Figs. 1 and 2, there is aset of arms on each side of of the box extending downwardly to the doors, and the above description of one set applies to both of them.

Only the lower ends of the chains 9 are shown, as these form a part of the grappling means shown and described in the companion application, which grappling means forms no part of the present invention.

Now, he bottom doors 2 are supported by the respective hangers 10, which hangers are, in turn, supported by the rod passing through the angle irons 11, as may be seen in Fig. 1. Thesedrop bottom doorsare similar and are of the same construction as those shown in the companion application. 1 The batch box is preferably rectangular in shape, and extending from side to side is a triangular compartment or chamber 12 having the base 13, and vthe sloping side walls 14:. This compartment 1is'ydesigned to act as a tank for-water so that-the water may be allowed to flow out with; the aggregates as the latter are discharged from the bucket.

Byhaving the tank built rightin the batch box, the advantage over the old method will be seen, as the water can be weighed or measured and charged into the tank of the batch box at a point on the job where the water would be easily available and there would not be the delays caused by troubles with pumps and long feed lines.

This tank or compartment for the water may be an integral structure provided with the an le irons 15 so that rivets may pass through these angles and through the sides of the batch box.

The base 13 of the tank or chamber forms the central bottom ortion of the box, and it will be seen that t e doors, when they are swung closed, abut against this base and underlie the same. This compartment, therefore, strengthens the box as in the former application, and divides the same into two hoppers to thus uide the aggregates in their egress from t e box. Furthermore, in this application I have provided a means whereby water held in this compartment may automaticall be discharged, as the doors are swung ownwardly to thus properly water the aggregates.

One of the guide members 4 to which the anns 3 are connected is serrated to form the rack 16 while near the bottom of the compartment in one of the sides, I have mounted a rotatable nipple 17 with the pinion 18 thereon to mesh with the rack 16. To this nipple will be secured the small elbow 19, and in this elbow is the short piece of pipe 20. When the doors are in the closed position, as shown in Fig. 1, the pipe 20 will be in an upright osition. As soon as the link mechanism is owered to thereby allow the doors to swing open, the rack will revolve the pinion and thereby revolve the nipple and pipe 20, to its dotted line position, so that the water may now escape from the compartment through this nipple and ipe.

It will be on erstood that when the doors are closed and the pi e 20 in its upright position and either be ore the aggregates are placed in the box or at any convenient time, an inlet pipe (not shown will be connected to the short pipe 20 an the compartment filled. Tolallow the air in the compartment to escape asthe compartment is filled, I provide a small vent 21 near the upper end there- 0 It will be appreciated that although I have shown a rack and pinion revolving a small pipe from an upright to a lowered position, a vave of any preferred form might be placed in here instead of the pipe shown, so that as the guide member with its rack portion raises, it would turn off the valve, and as the rack lowers, it would turn the pinion and open the valve.

From the foregoing it will be seen that I have provided a batch box of the bottom door type and provided link mechanism for opening and closing the doors, together with means whereby water stored in a compartment in the batch box may be discharged as the doors are opened.

The batchbox is one which is especially strong in structure, and the tank or compartment, besides strengthening the box, will assist in guiding the material in its egress from the box. Also, the compartment forms a tank for the storage of a measured amount of water which will be liberated when the doors are opened.

Lastly, the discharge of the water is accomplished automaticall so there is no chance of an operator ailing to feed the water to the aggregates, nor failing to feed the proper amount of water to the aggregates.

Many slight changes might be made without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A batchbox having drop bottom doors, a water compartment in said batchbox, means connected to the doors for opening and closing the same, and means connected with said first-mentioned means for allowing the escape of water from said compartment when the first said mentioned means are operated.

2. A batchbox having drop bottom doors, supports for holding the doors in closed position, a water compartment in the batchbox, and an automatic discharge mechanism connected with the doors for the compartment whereby the tank will be discharged as the doors are opened.

3. A batchbox having drop bottom doors and a compartment for the storage of water, a discharge means for the water compartment and so connected with the doors that as the doors are opened the discharge is opened, and as the doors are closed the discharge is closed.

4. A batchbox having drop bottom doors, a water compartment in said batchbox, link mechanism connected to the doors for opening and closing the same, a discharge for said compartment and the said discharge operably connected with the link mechanism, whereby the discharge is operated when the doors are opened.

5. A batchbox having drop bottom doors, a water compartment in said batchbox, link mechanism connected to the doors, a discharge for said compartment, means operably connected with the link mechanism whereby the discharge will open when the doors are opened, and the discharge is closed by the closing of the doors.

6. A batchbox having doors, means con-- nected to the doors for opening and closing the same, a Water compartment in said batchbox, a discharge for said compartment provided with a pinion, a rack connected with the 7 means for opening and closing the doors and operating said pinion to thereby open the discharge as the doors are opened.

7. A batchbox having doors, link mechanism connected to the doors for opening and closing the same, guide bars for said link mechanism, one of said guide bars being in the form of a rack, a water compartment in said batchbox and a discharge for said compartment provided with a pinion, and said pinion meshing with said rack to thereby open and close the doors asthe link mechanism is operated.

8. A batchbox having drop bottom doors, said doors partly closing the bottom of the batchbox a water compartment formed in said batchbox and the base of the compartment forming the remainder of the bottom of the batchboX, a revolvable pipe connected with said compartment, link means for opening and closing the doors, means connected with said link mechanism for swinging the pipe downwardly as the doors are opened, and swinging the pipe to an upright position when the doors are closed.

In testimony whereof I affix my signature.
